It amazes me that this language was supposedly written to be the groundwork for an entirely new html engine and yet there has never been a really nice HTTP library; built in or third party. Look at some of the last language hype parties: Node and Go; they both didn't even hit alpha stage before they had fantastic HTTP/networking libraries built in.
I get that Rust is targeting low-level, "systems" programming, but I really don't see how you can't also be a very performant server language.
